10. Consider an MA process x(n) of order two described by the difference equation x(n) = v(n) + 0.75 v(n − 1) + 0.75 v(n − 2), where v(n) is a zero-mean white-noise process of unit variance. The requirement is to approximate this process by an AR process u(n) of order M. Do this approximation for the following orders: (a) M = 2. (b) M=5. (c) M = 10. Comment on your results. How big would the order M of the AR process u(n) have to be for it to be equivalent to the MA process x(n) exactly?
